LUBRICATING APPARATUS.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed March 11, 1919. Serial No. 282,051.

To all whom it may concern Be it known that I, HANS I'IANSEN, of Valkyriegaten l3, Christiania, in the Kingdom of Norway, have invented certain new and useful Improvements in Lubricating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to ball valves for lubricating a 'iparatus of the kind, in which a kind of dancing or oscillating motion is imparted to the valve ball through the movement of the mechanism to he lubricated (railway or trau'iway cars or the like), the ball valve hereby intcrmit tentl y opening and shutting of? the oil supply.

Now according to this invention I make use of a valve seat for such ball valves, which is surrounded by a secondary oil receptacle or pocket, the bottom of which is situated so much lower than the valve seat, that the impurities contained in the oil are allowed to settle on the bottom of this receptacle, and therefore can not be deposited on the edge of the valve seat.

In the accompanying drawings Figure 1 is a vertical section through a lubricating apparatus provided with my improved valve, and Fig. 2 is a corresponding sectional view of the valve on an enlarged scale.

Referring now to the accoi'npanying drawings l is an oil cup or primary receptacle for the lubricant, from which cup the oil is as well known fed to a tube or receiver 2 by means of a wick 3. In the lower end of this tube or receiver 2 is arranged a valve seat 4 having the form of a high cone with its tip pointing upward, and with a central bore. On this valve seat el formed by the sharp edge between the outer face of the cone and the central bore rests a valve ball 5. The size of this ball 5 is in a well known is always by its weight and through striking against the inner walls of the tube 2 brought back to its valve closing position on the top of the cone.

The upwardly pointed valve seat is raised so much above the bottom of the tube 2 that there is formed a ring shaped secondary oil receptacle 7 surrounding the valve seat, said receptacle being by aid of the wick supply always kept filled with oil and being so deep that the impurities contained in the oil will have time to be deposited on the bottom of this ring shaped receiver, where'lrom it may be dislodged at long intervals by unscrewing the valve seat.

This combination of a-valve seat, where the motion of the valve ball owing to the sharp edge of the valve seat automatically removes any deposit of impurities from it, with a secondary oil receptacle from the upper, cleanest layer of which the oil fed through the valve is tapped, provides a very effective oil valve.

Claim:

In ball valves for lubricating apparatus, in which an oscillating or dancing movement is imparted to the valve by the motion of the mechanism to be lubricated, whereby to intermittently open and close the oil feed through the valve, the combination with a receptacle, a receiver tube and awick for conveying lubricant from said. receptacle to the top of said tube, of a valve seat and a valve seated thereon in the lower end of said tube, a secondary oil receptacle or settling chamber being formed below said valve seat. In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
